Title: Improvements in and relating to carburetters for internal combustion engines
IPC: F02M9/127
Filed: 1935-09-23
Abstract: 460,728. Spray carburetters. HEROLD, O. E. R., (trading as HEROLD, R., [Firm of]). Sept. 23, 1935, No. 26374. [Class 7 (iii)] Into an annular air channel which surrounds a nozzle stock provided with a metering nozzle, there run from the stock a number of fuel passages which terminate in sharp edged spraying nozzles or tubes projecting perpendicularly into the channel and at two places, the cross-sections of the air channel are regulated by a displaceable profiled member, the first place lying in the region of the fuel outlets and the second replacing the throttle valve. A vertically movable regulating member 6 controls simultaneously the cross sections of the air passage past radial fuel nozzles 11 and a passage between the lower edge 8 of the regulating member and a conical portion 9 of a nozzle stock 3, the control of this lower passage replacing the throttle valve. During idling the lower passage offers a minimum opening which is less than that of the upper passage, but the profiles of the stock 3 and member 6 are such that a small movement of the member 6 for starting widens the lower passage more than the upper, while further movement acts oppositely and the final displacement again gives greater widening to the lower passage. A support 15 raises the regulating member 6, a spring pressed ball 17 engaging in a stepped groove to indicate the final lean mixture position and a further position in which fuel is cut off and air only is supplied. The fuel, fed through a passage 5, enters a chamber 13a in a piston 13 in a chamber in the nozzle stock 3 and flows through ports 13b and a nozzle 4 to the spraying nozzles 11. These project into the air stream and have flared mouths inclined slightly upwards. The piston 13 is connected to the regulating member 6, and pumps fuel through the nozzles when the member 6 is raised, especially for starting. In the uppermost position of the piston, a plug 16b closes a passage 16c to cut off the fuel entirely. In a modification, the piston rod of the pump projects above the nozzle stock and is manually operated independently of the control member 6, which completely closes the second regulated passage or throttle, a byepass for idling being provided in the stock.

Abstract: 1,016,361. Electrolytic cell for polarization resistance measurement. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 25, 1964 [July 5,1963], No. 26722/63. Heading G1N. The rate of corrosion of a metal in a corrosive liquid environment, e.g. in chemical plant, boilers, power station plant, pipelines or structural steelwork, is tested by measuring the polarization resistance in a cell comprising a first electrode of said metal, a second electrode and the corrosive liquid environment, the change in potential of the first electrode being measured in comparison with a reference electrode also in contact with the corrosive liquid. The reference electrode 5 Fig. 3  (not shown) is situated in the current dead space within an annular electrode 4 of the metal under test (said first electrode), which preferably has an exposed area of at least ten times the exposed area of the reference electrode, mounted in one end of a sheath 1, e.g. of stainless steel, which may serve as said second electrode. The sheath may be sealed to a high pressure vessel 6, by a P. T. F. E. joint ring 9. The electrodes may be insulated from each other by P. T. F. E. sleeves 7, 8 and an epoxy resin filling 3 or, for high temperature use, the insulation may be entirely P. T. F. E. and water cooling (not shown) may be provided. A table is given of suitable metals for use as the reference electrode with various metals under test. Figs. 1 and 2 (not shown) exemplify other electrode assemblies. Fig. 4 shows a circuit enabling a valve voltmeter to be switched to measure the potential difference between the reference electrode (A) and the first electrode (B) for a given current between the first electrode and said second electrode (C), which current is deduced from the voltage drop across R 2 . The ohmic resistance of the cell may be separated from the polarization resistance by combining AC and DC measurements. The rate of change in potential difference between electrodes A and B with respect to the current between B and C indicates the rate of corrosion of electrode B. The invention may be used to measure continuously and record rates of corrosion and to operate a system for the automatic addition of a corrosion inhibitor as necessary.

Abstract: 206,499. Gould, R. Howe-. Nov. 3, 1922, [Convention date]. Secret and selective systems. -A message is transmitted with an irregular but periodic and continuous variation of wavelength to which the tuning of the receiving aerial is synchronized by means of a rotating cam. A motor 7 controlled by a governor 10 rotates a spindle 8 on which is mounted a cam 13, Fig. 2, having an irregular outline cor. responding to the variations in wave-length imparted to the transmitted message. The edge of the cam controls the setting of the vario-coupler 4, 6 through an arm 14. Before the commencement of transmission the switch 19 is moved over to connect up the circuit 12 coupled to a valve 21. A prolonged calling signal energizes a relay 22 and closes a local circuit containing a solenoid 24, the core 25 of which is fully raised against a dash-pot 26. At the cessation of the preliminary signal the core 25 drops freely, with sufficient momentum to depress a lever 25, and so clutch the spindle 8 to the driving-shaft of the motor 7. The dash-pot 26 prevents the core from being fully retracted by the effect of atmospheric or fortuitous signals. In a modification several cams similar to 13 are mounted on the spindle 8 and are arranged so that the receiving aerial may be tuned to one or other of various simultaneous transmissions on different basic wave-lengths.
